caja-owncloud package does not seem to work

I'm running Trisquel etiona 9 with Mate Desktop. I installed the ownCloud client and caja-owncloud from the command line. Owncloud-Cliente it seems to work, but the caja-owncloud extension that makes the integration of the owncloud-client with the caja does not work.

On another separate computer with plasma kde triskel the dolphin and dolphin-owncloud works normally according to the images.

I already tried to install these packages and the corresponding one for nautilus on trisquel mate but it didn't work either. I even cleaned the hidden folders and nothing.
